Abstract
864,476. Punching slots in plates. TRUMPF, C., [trading as TRUMPF & CO.]. May 14, 1957 16, 1956], No. 15261/57. Class 31 (2). [Also in Group XXII] A tool for cutting slots in a plastic or like sheet consists of a punch 16 having side-cutting edges co-operating with fixed blades 2, 3 mounted in a support I and an end-cutting edge co-operating with a transverse blade 10 mounted in the support 1 so as to be movable from an operative position in which it produces a lateral cut extending between the main cuts produced by the fixed blades 2, 3 to an inoperative position to one side of the punch 16. One of the fixed blades 2 is secured by a screw 4 in the support 1 and the other is adjustably held in the support 1 by a screw 5 locked by a collet 7. The movable blade 10 is moved by lever 12 or a remote control 14. The blades 2, 3 and the punch 16 are oppositely tapered in both the horizontal and vertical planes. The punch 16 has a transverse cutting edge 22 which co-operates with a fixed blade 15 in the support 1. The blade 10 is used to make the initial lateral cut at the beginning of the slot and is subsequently moved out of the way to facilitate passage of the waste chips over an inclined surface 23 of the support 1.
